3M Wire Terminals
RSP Supply carries a complete selection of 3M wire terminals designed for secure, high-performance electrical connections in industrial, automotive, and commercial environments. Built for durability and long-term reliability, 3M wire terminals ensure safe and efficient wiring installations even in demanding conditions.
As a trusted name in electrical connection technology, 3M offers multiple terminal lines, including Highland and Scotchlok, which deliver consistent, high-quality crimps that resist vibration, corrosion, and wear. Each terminal features precisely molded insulators to promote proper tool alignment and ensure a solid crimp every time. Whether you’re working with ring terminals, spade connectors, or quick disconnects, 3M terminals provide dependable conductivity and mechanical strength that meet or exceed UL standards.
Available in PVC, nylon, and uninsulated options, 3M wire terminals support a wide range of wire gauges and installation requirements. Heat-shrink and high-temperature models are also available for applications that require extra protection against moisture, chemicals, or temperature fluctuations.
